Diketene is an organic compound with the molecular formula C4H4O2, and which is sometimes written as (CH2CO)2. It is formed by dimerization of ketene,...

may be prepared by the hydrolysis of diketene. Its esters are produced analogously via reactions between diketene and alcohols, and acetoacetic acid can...

[(C6H4)(CO2)2(C2H4)]n + 2n CH3OH A subset of transesterification is the alcoholysis of diketene. This reaction affords 2-ketoesters. (CH2CO)2 + ROH → CH3C(O)CH2CO2R Alkenes...

work on the reaction in 1887. The reaction has often been displaced by diketene-based chemistry, which affords acetoacetic esters. At least one of the...

large scale, methyl acetoacetate is industrially produced by treatment of diketene with methanol. Methyl acetoacetate has low toxicity to animals. It is highly...

Lonza converted most of its ketene to diketene, which was then converted to a range of chemical precursors. Diketene capacity rose to 18'000t per year in...

propen-2-yl acetate: At room temperature, ketene quickly dimerizes to diketene, but the ketene can be recovered by heating: Ketenes can react with alkenes...

large scale, ethyl acetoacetate is industrially produced by treatment of diketene with ethanol. The small scale preparation of ethyl acetoacetate is a classic...

dyes and pigments. For example 4-amino-2-benzimidazolinone condenses with diketene to give the acetoacetanilide, which undergoes diazo coupling with various...

Chloroacetone may be synthesized from the reaction between chlorine and diketene, or by the chlorination of acetone. Chloroacetone is used to make dye couplers...
